Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Broken endodontic instruments are common. Microscopes and ultrasonic devices significantly improve the removal of these fractured files during root canal therapy, minimizing complications.

Area of Science:

Endodontic therapy
Dental materials science

Background:

Broken instruments are a frequent complication in endodontic therapy.
Advancements in dental microscopy have improved visualization during root canal treatments.
Ultrasonic appliances are increasingly used for managing complications like fractured instruments.

Purpose of the Study:

To discuss the causes of instrument separation during root canal procedures.
To outline effective methods for removing broken endodontic instruments.
To highlight potential challenges and solutions when using ultrasonic devices for instrument retrieval.

Main Methods:

Review of causes for instrument fracture in root canals.
Description of retrieval techniques utilizing ultrasonic devices.
